animals become inactive in the cold Insects go into an inactive period too but it often isn t when the temperature drops They rely on more dependable signals in the environment For example many insects can tell how much sunlight there s each day They use that to tell themselves when to shut down Bugs are cold blooded meaning that their inside temperature is the same as the outside They can t move much when it gets below 40 degrees Fahrenheit So they search for any warm place They re looking for protection These guys have been doing this for 300 million years so they don t really know they
